Preparation

• Slice the beef against the grain into 0.5 cm thick slices or 1-cm sticks. Transfer to a small bowl. Add soy sauce, peanut oil, and cornstarch. Gently mix well by hand until all the slices are coated with a thin layer of sauce. Marinate for 10 minutes while preparing the other ingredients.
• Combine all the ingredients for the sauce in a medium-sized bowl. Mix well.
• Add ¼ cup water into a large nonstick skillet over medium-high heat until the water begins to boil. Add the broccoli and cover. Steam until the broccoli just turns tender and the water evaporates, about 1 minute. Transfer broccoli to a plate. Wipe the pan with a paper towel if there’s any water left.
• Add the oil and swirl to coat the bottom. Heat over medium high heat until hot. Spread the steak in a single layer. Allow to cook without touching for 30 seconds, or until the bottom side is browned. Flip to cook the other side for a few seconds. Stir and cook until the surface is lightly charred and the inside is still pink.
• Add the garlic and ginger. Stir a few times to release the flavor and fragrance.
• Return the broccoli to the pan. Stir the sauce again to dissolve the cornstarch completely and pour it into the skillet. Cook and stir until the sauce thickens, about 1 minute. Transfer everything to a plate immediately. Serve hot as a main dish.
